The batteries are retaine'din position lWithin this casing by "Too V'means of a'removable closure capii.l Ar

ranged between this Closure cap andthe metal bottom Wall ofthe A batteryis a coil 'spring `5 providing a connection between the negative side ofthe l`A'battery and 'the Walls off the casing throughth'e :cap 4. y

An upper fca'sing 6 is mounted upon the vupper end of the lower casing land has-'its outer 'end externally'th'readed to be engaged by ascreW 'Cap `'oarrying a/lensB and a re- A'f yfle'ctor 9,'the refleot'or'9 being preferably disposed between the upper edge ofthe Casing 6 and the edge ofthe lens 8 Yasbest illustrated in Fig. 1. vrlhisrefl'eot'or'carries a sooketil() in `which a light bulb 11 is arranged. The 'f7-:5 lightbulbll'has connection with the A battery through a spring Contact 12 carried by 'easingY 6. The circuit between the yA battery land the bulb is 'controlled through'the'medi-uin of manually operated means which Will 'fi-80 be more particularly hereinafter described. The upper end of the easing 1 is'internally threaded as at`13y to-receive a sooketpieoe 14 Which is provided'with a reoess-15 adapted to rreceive the inner endl of a spring'oontaet 16. 8'5

This Contact 16 'is provided `for connection `between anegative circular trerninalv 18 of the B battery vand the negative ilament of piece as best illustrated in Figs. land 12. 29o

A Contact iinger 17 is alsorcarried by -the 'socket piece 14 and has Connection' to `a contact pin 20 adapted vto beengaged by a depressible-contaetbutton 21 having an end portion 21 extendingthrough` an venclosure "95 20 carried by the casing 6. This Contact pin` 21 is carried by a strip 18 of Conductive inaterial carried by and insulated from casing This strip 18 ycircuit between the positive side of the A Y A battery Aas-loest illustrated in `Fig. l, the

negative side of the A battery being connected in circuit with the light bulb through the spring 5, cap 4, metal walls of the casings l and (i, and reflector 9.

The socket piece 14 has extending upwardly therefrom a sleeve 22 in which the tube 19 is tted, the lower end of this tube bein(y provided with a negative Contact pin 23 in contact with thecontact linger 16 and a positivo contact pin 24 engaged by a contact finger 16', asbest illustrated in Fig. 1.

This socket piece 14 further carries a grid condenser 25 which has one *side*V connected to the grid side 25 of the tube and which is further provided with an external shoulder 26 which supports a rheostat control ring 27. The interior of this control ring engages a rheostat resistance coil 28. Arranged above the shoulder 26 and supported upon the top portion of the socketpiece 14 is a collar 29 and attached to this collar are circumferentially arranged contact heads 30a to 3()e inclusive, the upwardly projecting vand inwardly curved ends 31 of which are adapted to engage contact pins 32a to 32e inclusive. These vcontact pins are connected to various elements of the device as will be best understood by-reference to the wiring diagram illustrated in Fig. 12. Y Y

` Supported upon the collar 29 is a stationary tickler coil 33 which encloses the tube 19. One end of this coil is connected to one of the phone tip sockets, hereinafter described through the medium of the contact head 30a and Contact pin 32a, the other end of this coil being connected to the plate side of the tube through the medium of the contact head 301 andcontact pin 32d Arranged in spaced relation. I with Vthe tickler coil is the stationary condenser plate 34 which is cylindrical in form and coated halfway around its outer surface with tinfoil or copperfoil. It will be noted from the construction illustrated in Fig. 1 that the lower ends of the tickler coil and the stationary condenser plate are maintainedin spaced relation by means of a ring 35 retained in position by means of the pins 32.

Surrounding the tickler coil 33 is a sliding tuning coil 36 having its outer endclosed as at 37 and provided with a pluralityof contact points 38 which are adapted to be engaged by' the inductanceswitch lever 39 carried by a knob 40 which is rotatably mounted rupon the closed end 37. This inductance switchilever 39 is connected in circuit with the minus filament of the tube through the medium ofthe with the stationary illustrated in Fig. 12. l

Rotatably mounted upon the stationary condenser plate is a movable condenser plate 41 connected in circuit with a suitable ground through the medium of thepcontact head 30e and contact pin 32". Attachedto the outer end of the movable condenser plate is an ane nular rim 42 having graduations 43 formed thereon with the inner edge of the rim 42 en gaging over vthe outer edge of the stationary condenser plate as best illustrated in Fig. 1.

The'A stationary condenser vplate 34 (Figs. 7 and 9) is provided at its outer end with an'V annular groove 44 which `extends annularly ofthe condenserr34 and which engages ten-- sion springs 45 carried by the movable condenser plate retaining this condenser plate in alignment with the stationary condenser plate'so that the movable condenser plate will rotate in av horizontal plane.

Referring againtothe sliding tuning coil 436 it will be noted that thereis provided'a plurality of tap wires 36 each of which are individually connected to the contact points 38. One end of thiscoil is connected in cir cuit with the aerial circuit through the medium of the contact head 30c and contact pin 95 32c through the medium of Va flexible lead 46, this lead being of a length to'perm'it proper sliding movement of the coil.V The con-nec'-V tion between the inductance switch 39 and the contact head 30b and the stationary condenser plate is likewise through the medium of a flexible lead 46 similar to the lead 46.

The rheostat control rim 27 is providedv with an arcuate slot 47 in which a guide pin 48 moves. This guide pin is carried by they .shoulder 2G of the socket piece 14 serving to limit rotary movement of the control rim 27.

It will be noted in Fig. 4 that the rheostat resistance coil 2S extendshalf way around the socket piece 14 and opposite this coil is arranged a copper strip 49-connected to the-Y positive iilament side Yof the tube through the contact finger 16. It is apparent from this -construction that when one of the spring contacts 50 or 51, carried by the control rim 27 is in engagement with the resistance coil, the other will be in engagementv with the copper ioo strip 49 thus completing a connection between Y y' Vthe rheostat resistance coil and the copper strip.

The socket vpiece 14 1s provided witha plurality of cordtip socketsfor connecting the device with the head phones, aerial 51, and ground 52. The cord'tip ysocket indicated at 52 connects one of the'phone tips, indicated Vby 56 to theL positive' side of the B battery phone tip 57 to the tickler'coi1f33-through` the medium of the contact head 30a and concompartment operatively connected to said bil " said socket.

tact pin 32a; the cord tip jack indicated at 54 connects the ground 52 to theV movable condenser plate; the cord tip jack 55 connects the aerial 51 to the gridcondenser 25 and to the tuning coil 36.

56 having a retaining rim 57 upon their inner f ends with a nut 58 upon the outer yends to retain the connection 59 thereon.
